is this an HPFP failure or something else ?

2007 335xi
I started to get longer cranks while starting the car yesterday and today.
While driving home tonight the car felt like it was going to stall while stoppped at a red light. Was close to home so only had to drive about 1 more minute and went slow. Turned engine off and restarted (a bit of a slow crank) and then drove it around the block, the Service Engine Soon (SES) came on but NOT the 1/2 engine light (malfunction engine light).
I parked the car and will take it to the dealer tomorrow.

With only the SES light on should I risk driving it to the dealership (about 20km) or get it towed ?

Do the above symptoms indicate that it is a HPFP failure or something else ?
(I've already had the HPFP replaced twice - in April 2009 and Feb 2011 and the turbo injectors have been replaced in May 2011).
Thanks.

SES light is orange right? I think if it's red it's not safe to drive. I've driven it to the dealership after a HPFP failure before too.
